Grounding Instructions
WARNING: Risk of electrical shock. In the event of a short circuit,
grounding reduces the risk of shock by providing an escape wire for
the electric current. This air compressor must be properly grounded.
This product should be connected to a grounded, metallic,
permanent wiring system, or an equipment-grounding terminal or
lead on the product.
DANGER: Risk of electrical shock. IMPROPER GROUNDING
CAN RESULT IN ELECTRICAL SHOCK.
Voltage and Circuit Protection
Refer to the Voltage and Minimum Branch Circuit Requirements
under Specifications.
• Voltage supply to circuit must comply with the National
Electrical Code.
• Circuit is not used to supply any other electrical needs.
Main Power Disconnect Switch
Install a main power disconnect switch in the line from the panel
to the compressor. The main power disconnect switch must be
located near the compressor, for ease of use and safety. When
turned OFF, the main power disconnect switch shuts off all power
to the compressor. When it is turned ON, the compressor will start
and stop automatically, controlled by the pressure switch.
Air Distribution System
WARNING: Risk of bursting. Plastic or PVC pipe is not designed
for use with compressed air. Regardless of its indicated pressure
rating, plastic pipe can burst from air pressure. Use only metal pipe
for air distribution lines.
INSTALLING AND DISCONNECTING HOSES
WARNING: Risk of unsafe operation. Firmly grasp hose in hand
when installing or disconnecting to prevent hose whip. Ensure regu-
lated pressure gauge reads 0 PSI.
The next figure represents a typical air distribution system. The fol-
lowing are tips to remember when setting up the air compressor's
air distribution system.
NOTE: Compressed air from oil lubed air compressors will contain
water condensation and oil mist. Several drains, traps and filters
will be needed to supply air without water (including aerosols) or oil
to spray equipment, air tools and accessories requiring filtered air.
Always read the instructions for the air tools and accessories being
used.
• Use pipe that is the same size as the air tank outlet. Piping that is
too small will restrict the flow of air.
• If piping is over 100' (30.5 m) long, use the next larger size.
• Bury underground lines below the frost line and avoid pockets
where condensation can gather and freeze. Apply pressure before
underground lines are covered to make sure all pipe joints are free
of leaks.
• A flexible coupling is recommended to be installed between the
globe valve/air discharge outlet and main air distribution line to
allow for vibration.
• A separate regulator is recommended to control the air pressure.
Air pressure from the tank is usually too high for individual air
driven tools.
• DO NOT install lubricators between the tank and any spray equip-
ment, air tool or accessory requiring oil-free filtered air.
• Drain all traps, filters and dirt legs daily.
